Open source. Open possibilities.

DeepTutor is an open-source lifelong personalized tutoring platform from HKUDS, combining agentic chat, knowledge bases with multiple RAG engines, guided learning, book generation, quizzes and multi-channel IM partners.

Curated archive of leaked system prompts from ChatGPT, Claude, Gemini, Grok, Copilot, Cursor, Perplexity and others, captured verbatim and organized by vendor with recent additions and change log.

Ruflo is an agent meta-harness for Claude Code and Codex that enables multi-agent swarms, self-learning memory, RAG integration, federation, and extensive plugin ecosystem to build coordinated AI workflows.

A local-first review surface for writing with AI coding agents, allowing users to annotate and edit documents while routing feedback back to the agent session.

Agentic OS is a self-hosted control plane for running business operations as a fleet of AI agents. It features a cost-aware LLM router, cross-module workflows, and human-in-the-loop approvals for finance, support, and compliance.

Local-first, auditable AI-assisted job-search workbench: JD analysis, application tracking and resume workflows with anti-fabrication safeguards, plus interview and offer pipeline. Markdown and CSV files, BYOK AI CLI, privacy-first.

Context Engineering Protocol provides AI coding-agent skills that assemble human-approved, source-attributed context packages — code graphs, requirements, org conventions, and constraints — before generation runs. It detects gaps, conflicts, and staleness across sources, gates output behind explicit human approval, and supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex.

An AI job application framework built on Claude Code that evaluates job postings, tailors CVs, writes cover letters, and preps interviews — all running locally on your machine.

Agent Relay is an MIT-licensed end-to-end encrypted inbox where AI agents deliver artifacts, drafts, and spend requests for human review. It offers a hosted service or self-hosting with PostgreSQL, S3 storage, passkey sign-in, agent API tokens, CLI/MCP tools, and an optional email approval relay.

Read-only-by-default Model Context Protocol (MCP) server for Microsoft SQL Server, providing metadata discovery, parameterized SELECT-only queries, execution plan analysis for slow query diagnosis, profile-based multi-connection configuration, and optional per-profile write access, shipped as a .NET NuGet tool.

Simgit provides disk-efficient, isolated Git worktrees using copy-on-write (CoW) for running multiple AI agents or parallel development on a single repository. It leverages native filesystem features (APFS, reflink) or fuse-overlayfs to minimize disk usage, offering significant savings compared to full worktree copies.

Local-first, Markdown-based agentic harness for product management: numbered vault folders hold meeting evidence, docs and task ledgers, while a canonical .agent/ registry drives workflows and skills across several AI runtimes.

UnrealAgentPlayer allows AI coding agents to drive the Unreal Editor for closed-loop self-testing via a C++ plugin and a Python MCP server.

Swarm is a local-first control plane for AI-agent development that monitors every Claude Code, Codex, Gemini, Grok, Aider, and opencode session on your machine — tracking live tool calls, token spend, cost, tasks, worktrees, and resources — with rules enforcement, a coordination ledger, and a unified dashboard.

CocoIndex is an open-source incremental indexing framework designed to provide AI agents and LLM applications with continuously fresh context by reprocessing only changed data.

cb365 is a command-line interface for Microsoft 365, providing scriptable access to services like tasks, mail, calendar, Teams, SharePoint, and OneDrive. It offers structured JSON output, robust authentication, and safety features, making it suitable for DevOps, IT admins, and AI agent integration.

Zikra is a self-hosted MCP memory server for AI coding agents and teams. It provides a shared, project-scoped memory layer across multiple agents, with role-based access, hybrid semantic and keyword search, structured memory types, and optional PostgreSQL storage.

Orrery is an architect-first orchestration system for coding agents, ensuring precise model pinning, consented writes, and fail-closed operations. It delegates implementation to specialized AI roles (Astra, Terra) while the human architect retains control over requirements, architecture, and verification, with a read-only advisor (Sol) for final review.

Slopcamera is a local visual studio for coding agents: a Bun CLI, TypeScript SDK and Agent Skill that let agents author scenes, combine generated and recorded media, and export images, diagrams, animation and video while keeping editable sources.

Ralph is an autonomous AI development loop for Claude Code that runs continuous iterative coding cycles with intelligent exit detection, rate limiting, circuit breakers, session continuity, and GitHub issue/PRD import.
